1、Arctic MeltEarth\'s North ａｎｄ　South Poles are famous fｏｒbeing cold ａｎｄ　icy. Last year, however, the amount of ice in the Arctic Ocean fell to a record low. Normally, ice builds in Arctic waters around the North Pole each winter ａｎｄ　shrinks during the summer. But fｏｒmany years, the amount of ice left by the end of summer has been declining. Since 1979, each decade has seen an 11. 4 percent ｄｒｅｐin end of summer ice cover. Between 1981 ａｎｄ　2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner. Last summer, Arctic sea ice reached its skimpiest levels yet. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. ａｎｄ　it\'s a very large 23 percent below the previous record low, which was ｓｅｔjust 2 years ago. This continuing trend has scientists concerned. There may be several reasons fｏｒthe ice melt, says Jinlun Zhang, an oceanographer at the University of Washington at Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice ａｎｄ　open water. Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water ａｎｄ　the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.5℃ warmer than average ａｎｄ　1.5℃ warmer than the previous record high. With both air ａｎｄ　water getting warmer, the ice is melting from both above ａｎｄ　below. In some parts of the Beaufort Sea, north of Alaska ａｎｄ　western Canada, ice that measured 3. 3 meters thick at the beginning of the summer measured just 50 centimeters by season\'s end. The new measurements suggest that melting is far more severe than scientists have seen by just looking at ice cover from above, says Donald K. Perovich, a geophysicist at the U. S. Army Cold Regions Research ａｎｄ　Engineering Laboratory in Hanover, N. H. Some scientists fear that the Arctic is stuck in a warming trend from which it may never recover. Why is the ice melting from both above ａｎｄ　below?【单选题】

A.Because extra heat warms the air.

B.Because extra heat warms the water.

C.Because the temperature above the water is higher.

D.Both A ａｎｄ　B.

正确答案:D

答案解析:根据第7段第1句With both air ａｎｄ　water getting warmer可知。

2、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight ｏｒshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science fｏｒwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun ａｎｄ　colder as we travel _____ from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell ａｎｄ　Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fｏｒtheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】

A.by

B.away

C.along

D.with

正确答案:B

答案解析:本题难度较大，考查词义辨析，干扰项干扰较大。根据上下文逻辑，文章此处是说“当我们飞离太阳时温度会变得更低”，答案是B。

3、People can not understａｎｄ　the killer\'s motive to commit murder. 【单选题】

A.reason

B.expectation

C.argument

D.target

正确答案:A

答案解析:reason:理由、原因、动机，与原句中motive的意思相近；expectation：期望、展望、期待；argument:争论、辩论、论据；target：靶子。

4、Waving With LightIn the Sierra Madre mountain range of west central Mexico, the native Huichol people live much the way their ancestors did without electricity. That\'s because it\'s too expensive to string power lines to the remote mountain areas where they live. To help support themselves, the Huichol create beautiful artwork. They sell their art in cities hundreds of miles away from their villages. ａｎｄ　without electricity at home ｏｒon the road, they can only work during daylight hours. When it gets dark, they must stop whatever they\'re doing. Now, a team of scientists, designers, ａｎｄ　architects are using new technologies to provide the Huichol with light after the sun sets. The scientists\' technique involves weaving tiny electronic crystals into fabrics that can be made into clothes, bags, ｏｒother items. By collecting the sun\'s energy during the day, these lightweight fabrics provide bright white light at night. Their inventors have named the fabrics "Portable Lights." Portable Lights have the potential to transform the lives of people without electricity around the world, says project leader Sheila Kennedy. "Our invention," Kennedy says, "came from seeing how we could transform technology we saw every day in the United States ａｎｄ　move it into new markets fｏｒpeople who didn\'t have a lot of money."At the core of Portable Light technology are devices called high-brightness light-emitting diodes, ｏｒHB LEDs. These tiny lights appear in digital clocks, televisions, ａｎｄ　streetlights. LEDs are completely different from the light bulbs. Most of those glass bulbs belong to a type called incandescent lights. Inside, electricity heats a metal coil to about 2,200 degrees Celsius. At that temperature, bulbs give of flight we can see. Ninety percent of energy produced by incandescent lights, however, is heat ａｎｄ　invisible. With all that wasted energy, bulbs burn out quickly. They are also easily broken. LEDs, on the other hand, are like tiny pieces of rock made up of molecules that are arranged in a crystal structure. When an electric current passes through an LED, the crystal structure produces light. Unlike incandescent bulbs, they can produce light of various colors. Within an LED, the type of molecules ａｎｄ　their particular arrangement determines what colｏｒis produced. What does Sheila Kennedy say about Portable Lights?【单选题】

A.This invention can change the lives of people, both rich ａｎｄ　poor.

B.They are widely used in the United States.

C.Portable Lights can help poｏｒpeople around the world to get light.

D.They are expensive to make but easy to carry.

正确答案:C

答案解析:短文的第4段和第5段提供了答案。短文第4段的句子说了Portable Lights可以在世界范围内改变穷乡僻壤用不上电的人们的生活，选项C准确地表达了这层意思，所以是答案。A不是答案，说Portable Lights能改变富人和穷人的生活，不符合原文的意思。短文没有提及Portable Lights在美国使用，也没有说Portable Lights是否花费很大。所以B和D都不是答案。

5、Some Unusual CelebrationsSome holidays are well - known all around the world. Among them are New Year\'s Eve celebrations. Also common are days in honｏｒof love ａｎｄ　friendship, like Valentine\'s Day. Each country has its own special holidays too, often to mark important events in its history. Schools, banks ａｎｄ　government offices all close on days like these. Some of the days people celebrate, however, are less serious. A few of them are really very strange.Of course, they are not strange to the people who celebrate them. Perhaps that is because the celebrations have long traditions. Consider April Fool\'s Day, fｏｒexample. No one knows when ｏｒwhy it began. Today it is celebrated in many countries—France, Englａｎｄ　ａｎｄ　Australia, among others. On this day, people play practical jokes. Jokes are supposed to be funny, but these jokes do not make everyone laugh. The ones who laugh are the ones playing the jokes. The people they fool often get angry. Does celebrating this day make sense to you?Dyngus Day in Polａｎｄ　seems strange too. On this day, it is traditional fｏｒboys to pour water over the heads of girls. Here is the strangest part, they do it to girls they like.Other unusual celebrations take place in a single city ｏｒtown. A holiday called La Tomatina is celebrated in Bunol, Spain. Every year, in late August, big trucks carry more than 200,000 pounds of tomatoes into this little town. Then begins the world-s biggest food fight. Fｏｒtwo hours, people in the streets throw tomatoes at each other. Everyone ends up red from head to toe.August 10 marks the start of the Puck Fair, an Irish festival with a very unusual tradition. People from the town of Killorglin go up into the mountains ａｎｄ　catch a wild goat. They bring him back to town, put a crown on his head, ａｎｄ　make him king fｏｒthree days.There are also some celebrations that are really strange. In the United States, sometimes one person gets an idea fｏｒa new holiday ａｎｄ　tries to get others to accept it. Whose idea was Public Sleeping Day? That one is on February 28. It may seem strange, but it sounds like more fun than the one on February 29. _____Do you like the idea of inventing a new holiday? If you do, then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day.【单选题】

A.They bring him back to town, put a crown on his head, ａｎｄ　make him king fｏｒthree days.

B.Some of the days people celebrate, however, are less serious.

C.That is supposed to be Toothache Day.

D.Then begins the world-s biggest food fight.

E.Some people have fun imagining new holidays.

F.Jokes are supposed to be funny, but these jokes do not make everyone laugh.

正确答案:C

答案解析:本题有一定难度，根据上下文逻辑，此处讨论的是美国的奇怪节日，回来看剩余的选项，只有C符合上下文逻辑，是答案。

6、Stress Lessen CourseDoreen Sykora is now a juniｏｒat McGill University. She had a difficult time when she first began college. She said, "I was always well prepared fｏｒmy examinations. But I would go in to class to take the exam, ａｎｄ　I would fall apart. I could not answer the questions correctly-even though I knew the answers! I would just blank out because of nervousness ａｎｄ　fear". Histoshi Sakamoto, an anthropology student at Temple University in Tokyo reports similar experiences. These two young students were experiencing something called test anxiety. Because when a student worries ａｎｄ　is stressed about a test, his ｏｒher mind does not work as well as it usually does. The student cannot write ｏｒthink clearly because of the severe tension ａｎｄ　nervousness. Now there are special university courses to help students. In these courses, advisors ａｎｄ　psychologists try to help students by teaching them to manage test anxiety. Such a course helps students learn to live with stress ａｎｄ　not fail because of it. First students take a practice test to measure their worry level. If the tests show that their stress level is high, the students can take a short course to manage the fear. These courses teach students how to relax their bodies. They get training to become calm in very tense situations. By controlling their nervousness, they can let their minds work more easily. Learned information then comes out without difficulty on a test. Doreen Sykora saw immediate results after taking such a course. She now has enthusiasm about the relaxation methods. "Mostly, what I do is imagine myself in a very calm place. Then I imagine myself picking up a pencil. I move slowly ａｎｄ　carefully. I breathe easily ａｎｄ　let all the tension out. With each breath, more worry leaves me. It really works too. My grades have improved greatly! I\'m really doing well at McGill now. This relaxation method works not only on examinations, but it has improved the rest of my life as well". FｏｒHistoshi in Tokyo, the results were much the same. He is enjoying school a lot more ａｎｄ　learning more. What\'s the organization of the passage?【单选题】

A.Examples-theories-ideas.

B.Problem-strategy-result.

C.General statement-examples-result.

D.Strategy-experiment-examples.

正确答案:B

答案解析:第1段提出了两个同学的问题，接下来学校有了这样帮助学生的课程，最后讲了帮助的效果。因此选B。

8、Inventｏｒof LEDWhen Nick Holonyak ｓｅｔout to create a new kind of visible lighting using semiconductｏｒalloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes, ｏｒLEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights ａｎｄ　other everyday technology. On April 23,2004, Holonyak received the $500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the lOth year that the Lemelson-MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors. "Anytime you get an award big ｏｒlittle. It\'s always a surprise. " Holonyrak said. Holonyak, 75, was a student of john Bardeen, an inventｏｒof the transistor, in the early 1950s. After graduate school, Holonyak worked at Ben Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches. Later, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to generate invisible light, he wanted to generate visible light. The LEDS he invented in 1962 now last about 10 times longer than incandescent bulbs, ａｎｄ　are more environmentally friendly ａｎｄ　effective. Holonyak, now a professｏｒof electrical ａｎｄ　computer engineering ａｎｄ　physics at the University of Illinois, said he suspected that LEDs would become as commonplace as they are today, but didn\'t realize how many uses they would have. "You don\'t know in the beginning. You think you\'re doing something important. You think it\'s worth doing, but you really can\'t tell what the big payoff is going to be, ａｎｄ　when, ａｎｄ　how. You just don\'t know, "he said. The Lemelson. MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson-MIT Lifetime Achievement Award fｏｒher work on a new generation of "molecular sieves", that can separate molecules by size. Holonyak believed that his students that were working with him on the project would get the Lemelson-MIT Prize sooner ｏｒlater.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:需要注意题干中出现的修饰词sooner ｏｒlater（迟早）。利用题干中提到的新信息一他的学生，作为答案线索。在下文的内容中也没有看到有关“Holonyak对其学生的期望”的话语，因此选C。

9、Storms Sink ShipsRescuers have found the bodies of over 130 people killed in two ferry disasters in Bangladesh. The accidents happened during a storm that hit the country on April 21. Hundreds more are missing ｏｒfeared dead. The two ferries sank in different rivers near the capital city of Dhakfi as strong winds ａｎｄ　rain hit the South Asian country. The government has since banned all ferries ａｎｄ　other boats from traveling at night during the April-May stormy season. One of the ferries, MV Mitali, was carrying far more people than it was supposed to. About 400 passengers fitted into a space made fｏｒjust 300, police said. The second ferry carried about 100 passengers. "The number of deaths is certain to rise." said an official in charge of the rescue work. "No one really knows how many people were on board the ferry ｏｒhow many of them survived. Ferries in Bangladesh don\'t always keep passenger lists, making it difficult to determine the exact number of people on board. Besides the ferry accidents, at least 40 people were killed ａｎｄ　400 injured by lightning strikes, falling houses ａｎｄ　trees ａｎｄ　the sinking of small boats. Storms are common this time of year in Bangladesh, as are boating accidents. Ferry disasters take away hundreds of lives every year in a nation of 130 million people. Officials blame these river accidents on a lack of safety measures too many passengers in boats ａｎｄ　not enough checks on weather conditions. Ferries are a common means of transport in Bangladesh. It is a country covered by about 230 rivers. Some 20,000 ferries use the nation\'s Waterways every year. ａｎｄ　many of them are dangerously overcrowded. Since 1977, more than 3,000 people have died in some 260 boating accidents.How many people have been found dead in the two ferry disasters?【单选题】

A.Over 130.

B.At least 40.

C.About 400.

D.Over 3,000.

正确答案:A

答案解析:第1段第1句说到“救援人员已经找到了在孟加拉国的两次渡船失事中的130多人的尸体”。当然，实际的死亡人数还要高。
